**FastAPI** 提供了以下内容：

### 基于开放标准


* 用于创建 API 的 <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a> 包含了<abbr title="也被叫做: endpoints, routes">路径</abbr><abbr title="也叫做HTTP方法, 例如 POST, GET, PUT, DELETE">操作</abbr>，请求参数，请求体，安全性等的声明。
* 使用 <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (因为 OpenAPI 本身就是基于 JSON Schema 的)自动生成数据模型文档。

### Kontrol Edelim

Tarayıcınızı açıp <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a> bağlantısına gidin.

Şu şekilde bir JSON yanıtı ile karşılaşacağız:

```JSON
{"message": "Hello World"}
```

## ইনস্টলেশন প্রক্রিয়া

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

আপনার একটি ASGI সার্ভারেরও প্রয়োজন হবে, প্রোডাকশনের জন্য <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> অথবা <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.

**Typer** é o irmão menor do FastAPI. E seu propósito é ser o **FastAPI das _CLIs_**. ⌨️ 🚀

## Requisitos

FastAPI está nos ombros de gigantes:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> para as partes web.

## Instalación

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

También vas a necesitar un servidor ASGI para producción cómo <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> o <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.

You can probably right-click each link and select an option similar to `Save link as...`.

**Swagger UI** uses the files:

* <a href="https://cdn.jsdelivr.net/npm/swagger-ui-dist@5/swagger-ui-bundle.js" class="external-link" target="_blank">`swagger-ui-bundle.js`</a>
* <a href="https://cdn.jsdelivr.net/npm/swagger-ui-dist@5/swagger-ui.css" class="external-link" target="_blank">`swagger-ui.css`</a>

    /** 現在参照している要素のインデックス */
    protected int index = 0;

    /**
     * for each構文で使用するために配列をラップした{@link Iterable}を返します。
     *
     * @param <T>
     *            列挙する要素の型
     * @param items
     *            イテレートする要素の並び。{@literal null}であってはいけません
     * @return 配列をラップした{@link Iterable}
     */
    public static <T> Iterable<T> iterable(final T... items) {
        assertArgumentNotNull("items", items);

 * <p>
 * Unlike {@link ModelSource}, this interface supports loading of parent POM(s) from the same backing store and allows
 * construction of MavenProject instances without the need to have parent POM(s) available from local or remote
 * repositories.
 * <p>
 * ModelSource2 instances are cached in {@link ModelBuildingRequest#getModelCache()}. Implementations must guarantee
